9. Arithmetic Operator Name Example Result + Addition $x + $y
Sum of $x and $y -
Subtraction
$x - $y
Difference of $x and $y *
Multiplication
$x * $y
Product of $x and $y /
Division
$x / $y
Quotient of $x and $y %
Modulus
$x % $y
Remainder of $x divided by $y

10. Assignment Assignment Same as... Description x = y
The left operand gets set to the value of the expression on the right
x += y
x = x + y
Addition
x -= y
x = x - y
Subtraction
x *= y
x = x * y
Multiplication
x /= y
x = x / y
Division
x %= y
x = x % y
Modulus

11. Comparison Operator Name Example Result == Equal $x == $y
Returns true if $x is equal to $y !=
Not equal
$x != $y
Returns true if $x is not equal to $y
<>
$x <> $y
>
Greater than
$x > $y
Returns true if $x is greater than $y
<
Less than
$x < $y
Returns true if $x is less than $y
>=
Greater than or equal to
$x >= $y
Returns true if $x is greater than or equal to $y
<=
Less than or equal to
$x <= $y
Returns true if $x is less than or equal to $y

12. Increment / Decrement Operator Name Description ++$x Pre-increment
Increments $x by one, then returns $x
$x++
Post-increment
Returns $x, then increments $x by one
--$x
Pre-decrement
Decrements $x by one, then returns $x
$x--
Post-decrement
Returns $x, then decrements $x by one

13. Logical Operator Name Example Result and And $x and $y
True if both $x and $y are true or Or
$x or $y
True if either $x or $y is true
xor
Xor
$x xor $y
True if either $x or $y is true, but not both
&&
$x && $y ||
$x || $y !
Not
!$x
True if $x is not true

14. String Operator Name Example Result . Concatenation $txt1 . $txt2
Concatenation of $txt1 and $txt2 .=
Concatenation assignment
$txt1 .= $txt2
Appends $txt2 to $txt1

15. Array Operator Name Example Result + Union $x + $y Union of $x and $y==
Equality
$x == $y
Returns true if $x and $y have the same key/value pairs !=
Inequality
$x != $y
Returns true if $x is not equal to $y
<>
$x <> $y
